Sept. 11, 2008 | I have been dreaming about Sarah Palin. (Apparently, I'm not alone.) I wish I could say that I'd been conjuring witty, politically sophisticated nightmares in which she leads troops into Vancouver or kindergartners in the recitation of "Sinners in the Hands of an Angry God." But, alas, mine have been nonsensical, kiddie-style doozies in which she kidnaps my cats, or enjoys a meal with my girlfriends while I bang on the restaurant window. There's also a chilling one, in which a scary witch stands on a wind-swept hill and leers at me. What troubles me most...
